Also that is a good discussion in it self how many heroes are actually polite when they fight.

Superman and Wonder Woman of course always keep the social graces, but they are flexible. The Flash does not talk more then he needs to, all four earth GLs can shoot off at the mouth at times. Batman only says what he needs to, while his sidekicks handle the quips. Booster Gold has made mom jokes in a fight, and blue beetle had a smart mouth. Martian Manhunter has always seemed like the type to never stoop to that level, and Aquaman has outright called villians dumb to their face.
